Original Medicare doctor bills

Medicaid work
$22,557 in 2024
Medicaid paid $22,557 for 527 billed services this clinician did in 2024, up to 38 people in a month for one service.
Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid
This is pharmacy cost, not the office bill, and not what patients paid.
Opioids were 0% of their 11 Part D prescriptions in 2016. Too few prescriptions to judge: with under about 50 a year, a handful of patients can swing this share.
Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.
Year by year

| 2015 | 12 | None | 0% (0) | None | $1,037 |
Part D prescriptions only. A drug prescribed to fewer than 11 people in a year is hidden.

A payment is not proof that care is biased.
